Zur Prüfung, wie sich verschiedene Benzimidazolderivatc beim Aufbewahren verhalten, wurde folgender Versuch durchgerührt. Die Zersetzung der drei folgenden Verbindungen /u dem unsubstituierlen Grundkörper in Abhängigkeit von der Zeit wurde mil dem Lösungsmittel dcuteriertes Dimethvlsulfoxid Wasser gemessen.To test how various benzimidazole derivatives behave on storage, the following experiment was carried out. The decomposition of the following three compounds / u of the unsubstituted parent structure as a function of time was measured using the solvent-disintegrated dimethyl sulfoxide water.

Das Ergebnis zeigt, daß die Verbindung Il I im polaren Medium Wasser schneller in BCM übergeht als die Verbindungen I und II. Die Zerfallsdauer von mehreren Tagen ist jedoch noch ausreichend groß, um eine gute Wirkung in der Praxis zu erreichen. Die Verbindung I kann als Transportform des Wirkstoffs BCM in die pflanzliche Zelle angesehen werden.The result shows that the compound II I converts more quickly into BCM in the polar medium water than the compounds I and II. However, the disintegration time of several days is still sufficient great to have a good effect in practice. The connection I can be used as a form of transport of the active ingredient BCM can be viewed in the plant cell.
Je schneller also ein acyliertes Benzimidazol-Derivat (I. Il oder III) nach erfolgter Aufnahme in der Pflanze in BCM übergeht, um so besser muß sein Wirkungseintritt sein.So the faster an acylated benzimidazole derivative (I., II or III) passes into BCM after absorption in the plant, the better its onset of action must be be.
